There’s been a great resource that I’ve been using for a few months now called
AoS Reminders.

You basically tell the site what you’re including in your army, so your traits, command abilities, units etc, and it creates a list of reminders for you based on what phase the game is in.
I think its a valuable tool for beginners and vets, casuals and competitors. Its been good for me to read up while building my army to form a gameplan, and to print out and keep handy while I play. Its really made my turns go by faster as I have a breakdown of what I need to do and when. I also like to read up before a game just to keep it fresh in my mind.
Highly recommend!
Here’s the developers blog entry that has some interesting stats about what armies are being built and such:
